Coldfusion & Jquery $.ajax form update question

I have a form... with rows of data. In those rows I have a select menu to where I can reorder the rows of data into different categories. When I click submit on adjusting various select menus. I run the following script...

	function reorder_data_in_categories() {

		var data = $("[id=dataCategory]").serialize();
		var datax = "order=" + data;

		alert(datax);

			$.ajax({
				 url: "app/inc/inc_categorization.cfm",
				 data: datax,
				 success: function () {
				 	getData();
				 },
				 error: function (xhr, ajaxOptions, thrownError) {
				 alert(xhr.status);
				 alert(thrownError);
				 }
		});

	};

Open in new window


my data for var "datax" looks like so...

order=category_247=96&category_248=95&category_249=95&category_250=95&category_251=95&category_243=95&category_245=95&category_246=95

Open in new window


only the first record is being updated probably because of the & signs and "Order" is defining the first value. Just trying to loop through all of the values to update all records in the data string.

On inc_categorization.cfm I have...

<cfloop index="x" from="1" to="#listLen(order, "&")#">

	<cfset package = listGetAt(order, x)>

	<cfset recordID = listGetAt(package,2,"_")>

	<cfset value = listGetAt(recordID,2,"=")>

	<cfset recordID = listGetAt(recordID,1,"=")>

	<cfquery stuff


</cfloop>

What about :
	function reorder_data_in_categories() {

		var data = $("[id=dataCategory]").serialize();
		var datax = { order: data };

		alert( JSON.stringify(datax) );

			$.ajax({
				 url: "app/inc/inc_categorization.cfm",
				 data: datax,
				 success: function () {
				 	getData();
				 },
				 error: function (xhr, ajaxOptions, thrownError) {
				 alert(xhr.status);
				 alert(thrownError);
				 }
		});

	};

ok, thx. I see the data is formatted into a json string but by cfm code (listed above) is now causing issues with the json format.

{"order":"category_249=95&category_250=95&category_251=95&category_243=95&category_245=95&category_246=95&category_247=95&category_248=95"}

Oh and I know that I'm suppose to use .cfc's as you directed (I think it was you :)  .. ) me a month ago or so which I have been doing in any new projects but for consistency for this project I'm using .cfm for the ajax calls.

I tried a couple of things. Just haven't worked with JSON data before. Is <cfset cfData=DeserializeJSON(theData)> maybe answer to get it back out of JSON? Anyways, I did try using it but It's not quite working right.

Try to replace :
var data = $("[id=dataCategory]").serialize();
            var datax = { order: data }
by :
var data = $("[id=dataCategory]").serialize().split("&");
            var datax = { order: data }

it will create a JSON objetc like that :
{
    object: ["category_249=95", "category_250=95", "category_251=95" ,...]
}

or maybe just :
var data = $("[id=dataCategory]").serialize().split("&");
            var datax =data;

so you just need to loop over the array

Cool! Worked. Thx leakim971! Just for those that need the guidance... I did need to add.
var data = $("[id=dataCategory]").serialize().split("&");
            var datax = "order=" + data;
